摘要

中文摘要: 针对底孔前水沙运动规律的特殊性，引入行进水深以及求解底部挟沙力的张瑞瑾公式方法，建立了能准确反映孔口泄流条件下局部水沙运动待性及河床形态变化过程的三维水沙数学模型

使模型能准确反映孔口泄流条件下局部水沙运动特性及河床形态变化过程。通过室内模型试验对模型中的悬沙计算模块以及推移质计算模块进行了验证，结果表明，模型可应用于水库坝前冲刷漏斗模拟。最后将模型应用于云南瑞丽江水库取水防沙效果分析中，并对水库取水排沙调度提出建议

Abstract

Abstract:Based on RNG model

the 3-D water and sediment model simulating the scouring funnel and water-sediment mixture flow in front of a reservoir dam was developed. Based on the flow characteristics in front of bottom orifice

the approach of water-depth and Zhang Ruijin formula were adopted to simulate the sediment carrying capacity near the riverbed. The results of model tests of movement of suspended sediment and of bed load were adopted to verify the developed model. Finally the model was applied to analyze the effect of water diversion and sand prevention of Shweli reservoir

Yunnan province and the results can assist in the decision of layout projection and reservoir management for the water diversion and sand prevention.
